Introduction

We pulled a couple of strings to acquire the most desirable Android phone today, the HTC Evo 4G!

Check out Wired's video of our HTC Evo 4G disassembly!

This teardown is not a repair guide. To repair your HTC Evo 4G, use our service manual.

  1. Today is a glorious day in the history of teardowns. We welcome the HTC Evo 4G to grandest stage of them all.
    • Today is a glorious day in the history of teardowns. We welcome the HTC Evo 4G to grandest stage of them all.

    • The Evo 4G's technical highlights include:

    • 1 GHz Qualcomm Snapdragon processor

    • 4.3 inch LCD Display

    • 512 MB RAM

    • Dual cameras (1.3 MP front and 8MP back)

    • HDMI output (requires adapter)

    • Android 2.1

  2. The top of the Evo's smooth-contoured rear case is dominated by an 8 Megapixel camera and its two LED flashes.

    • A flip-out stand on its bottom edge allows the Evo to sit horizontally for watching videos on the 4.3" behemoth of a display.

  3. After a bit of careful prying, the rear case easily pops off the Evo.

    • Holy red innards! Maybe it's because the Republic of China's flag is 3/4 red?

  4. Like most reasonable phones, changing the Evo's battery is a snap. The 3.7 V, 1500 mAh rechargeable Li-ion battery weighs in at 31 grams. That's 23% more capacity than an iPhone 3GS, 15% more than a Droid Incredible, and 7% more than a Nexus One.

  12. We used an iPod opening tool to separate the glass from the LCD and frame. Removing the glass is not terribly difficult with the Evo 4G. This is great news for those unfortunate enough to drop their shiny phone and crack the glass. Removing the glass is not terribly difficult with the Evo 4G.
